To all whom it man concern:

Referring to the drawings, 1 indicates the Be, it known that I,HOLLINGSWORTH B. longitudinal members and 2 the'transverse Banner, acitizen of the United States, residing at Shreveport, in the parish ofCaddo and Stateof Louisiana, have invented certain new and usefulImprovements in Aeroplanes; and I do hereby declare the follow; ing tobe a full clear and exact description of the invention, such as willenable others skilled in the art to which it appertains to same.

My invention relates to aeroplanes, and it consists in theconstructions, combinations and arrangements herein described andclaimed.

An object of my invention is to aeroplane having an improved sustainingplane constructed to provide a maximum sustaining power and stability.

A further object of my invention is to provide an aeroplane havingsimple and ellifor automatically maintaining stability. i

A further object of my invention is to provide an improved aeroplanehavin rautomatic stabilizing means adapted to act 'constantly and withcertainty under all practical conditions. A further object of myinvention is to provide an improved aeroplane having emergency means formaintaining a headway upon failure of the propeller drive.

A further object of my invention is to provide an aeroplane havingimproved guiding; means under control of the aviator.

In the accompanying drawings forming a part of this application, and inwhich similar reference symbols indicate corresponding parts in theseveral views :-Figure 1 is a plan view. illustrating one embodiment ofmy invention: Fig. 9 is an elevation of the construction shown in Fig. lFig. 3 is a detail side view of the sustaining plane and means foradjustably supporting one of the guide planes along the lateral edgethereof; Fig. 4 is a detail elevation ot' the gyroscope. partly brokenaway. to show the automatic-a1 clutch drive from the motor; Fig. 5 is asection on the line 55 of Fig. 4: Fig. 6 is a detail. view of the driveconnection between the gyroscopeand auxiliary propeller. parts beingbroken away for ol'earncss: Fig. 7 is a section on the line 7 -7 of Fig.6: and Fig. 8 is an enlarged fragmentary section of the means forlocking-"thegyroscope in its several adjusted position provide anmembers of a main frame, to which is strongly secured a sustaining planeformed with a downwardly-comave body portion 3 and terminating in aplane front portion 4 and an upwardly-turned rear portion 5; the framebeing mounted on groundwheols 6 and 7 adapted to incline the frontportion st of the plane slightly upward. when start ing on level ground.In this improved construction of plane. the air forced rearwardlv underthe upivardly-inclined front port-ioh,

4 thereof impinges strongly on the downwardly-concave body portion 3 andis gradually deflected thereby downwardlyacross the lower surface of therear portion 5 of the frame: the final upwardly curved surface of saidrcar portion 5 acting ctiectivcly to automatically prevent rearwarddiving of the plane upon stoppage of the propeller from any causc.Spaced stabilizingplanes 8 are rigidly secured to the sustaining planeand extend vertically from the upper and lower faces thereof. Thisprovides an improved and highly advantageous constructlon having amaximum sustaining power and stability.

l have shown seats 9 for an aviator and passenger supported on thesustaining plane in position to be effectively shielded by the concavebody portion 3 of said plane; suitable levcrs or other usual devicesbeing provided in convenient position for controlling the rudders andothcr parts in the Well known manner.

A main propeller l0 is journaled in a bearing .11 supported foruniversal movement on tho main frame; the shaft 12 of said propellerbeing connected by a universal joint 13 to a drive shaft l4 driven inanysuitable manner. as by bevel gears 15, by an air cooled motor 16preferably of the rotary reciprocating type. This provides a simple andeliicientconstruction by which the main propeller 10 can for varying itsaction to conditions.

A bracket 17 is be readily shifted meet all practical pivoted at 18 onthe main frame, and carries a gyroscope 19 and a.

lot

drive motor 20 therefor; said gyroscope be-' I ingr shown provided witha mini-mizin friction. The gyroscope spindle 21 is journaled in a block22 slidably mounted in a guide 23 curved concentrically with the pivot18; a nut, 24

closed casing for upper end of the being threaded on said block forclampingly engaging the upper face of said guide to firmly lock saidblock 22 in its several adiusted positions. I have shown an arm 25projectin from the nut 24, which can be connecte to a link extending inconvenient position for actuating by the aviator for locking andunlocking said nut. This provides an improved construction by which theplane of rotation of the gyroscope can be readily shift/ed'to insure thebest effect under all practical conditions such as starting on inclinedground, etc.

A shaft 26 is .,.driven by inter-meshing gears 27 carried in a hollowcap 28 supported-on the block 22; said shaft 26 extending slidably androtatably in a hollow shaft 29and being provided with a keyway 30 forreceiving a tooth. or key formed on one member of a detachable clutch31, 32. The hollow shaft 29 is connected by a universal joint 33 withthe spindle of an auxiliary propeller 34, whereby said propeller can bedriven by the gyroscope upon shifting of the clutch members 31 and 32into engagement by the aviator. This provides means by which theauxiliary propeller can be driven to maintain a headway upon failure orstoppage of the main propeller 10 from any cause, and as the gyroscope19 will run for a considerable length of time even upon accidentalstoppage of its motor 20, the auxiliary'propcller 34 could ordinarily bedriven for, a suliicient length of time to permita safe landing. Thegyroscope 19 is driven by any Well known form of friction clutch 35 topermit the continued free forward rotation of said gyroscope uponstoppage of its motor. I

Guiding planes 36 are pivoted at 37 to the main frame and providcd withblocks 38 and 39 slidably mounted in curved guides 40 and 41 mounted onthe main frame concentric with said pivot 37.; suitable connections,such as wires 42 and 43 being led to weaves a convenient position foractuating of said guiding planes by the aviator.

I have illustrated and described preferred and satisfactoryconstructions, but changes could be made within the spirit and scope ofmy invention.

1 claim Y 1. The combination with an aeroplane of a frame. pivotallymounted thereon; a curved guide bar mounted concentrically with thepivot of said frame; a gyroscope mounted on said pivoted frame, andhaving a shaft engaging with said curved guide bar; a device carried bythe gyroscope shaft for securing the same in adjusted positions on saidcurved bar; a propeller; a driving shaft having a universal jointconnecting the propeller with the gyroscope shaft and adapted to beadjusted therewith; and a motor mounted on the pivoted frame fordrivingthe gyroscope and the propeller, substantially as described. l

The combination with an aeroplane of a frame ,pivotally mounted thereon;a curved guide bar. mounted concentrically with the pivot of said frame;a gyroscope mounted on said pivoted frame, and having a shaft engagingwith said curved guide bar; a device carried by the gyroscope shaft forsecuring the same in adjusted positions on said curved bar; a propellershaft; a propeller mounted on said propeller shaft; a shaft comprisingslidably-engaging sections having a universal joint connection with thepropeller shaft; inter-meshing pinions connecting said gyroscope shaftand said sectional shaft; and a motor mounted on the pivoted frame fordriving the gyroscope and the propeller, substantially as described.
